2.2 Warning labels
The warning labels are made of soft PVC film, and are abrasion-proof, light-fast and resistant to
water and weathering. The design of the warning labels complies with the requirements of
ISO3864‑2 und ANSIZ535.4.
2.2.1 Warning labels on the LDU
Warning label W 201
Safe operation of the LDU
Safe operation of the LDU depends absolutely on the operator being familiar
with the user manual and safety instructions and putting them into effect.
Warning label - hazardous substances
Health risk
The flux and cleaning agents used may contain substances which are haz-
ardous to your personal health. Always wear your personal protective equip-
ment and observe the safety data sheet of the relevant flux or cleaning
agent.

Reaching into the LDU while it is running can lead to injuries to arms and
hands.

2.2.2 Important note on warning, prohibition and cautionary labels
WARNING
Warning labels
Do not use abrasive cleaners or solvents for cleaning warning labels.
Replace any missing, damaged or illegible warning labels. Please observe the correct posi-
tion of the warning labels.
2.3 Safety features
The LDU2X has an emergency stop button. When pressed, the power supply to motors of the
LDU2X is immediately interrupted. After releasing the emergency stop button the LDU 2X will be
in idle mode. To switch back to operation mode, a reference run must be conducted: See chapter
4.11
"Starting a reference run" [}71] or chapter 4.8 "Operating the control unit via user inter-
face" [}66].
WARNING
Placement machine and LDU2X have separate emergency circuits.
The emergency stop button of the LDU2X only interrupts the power supply to motors of
the LDU2X.
The emergency stop button of the placement machine interrupts the power supply to the
placement machine.
► Please ensure to press the correct emergency stop button in an emergency.

2.4 ESD guidelines
2.4.1 What does ESD mean?
Fig.1: ESD label
Almost all of the modules in use today are equipped with highly integ-
rated Metal-Oxide-Semiconductor (MOS) blocks and components.
The manufacturing techniques used mean that these electronic com-
ponents are extremely sensitive to overvoltage and thus to electro-
static discharge.
The abbreviation for such modules is "ESD" (Electrostatic Sensitive
Device). "ESD" is used internationally. The following symbol on cab-
inet rating plates, racks or packaging indicates that components
which are sensitive to electrostatic discharge have been used and
thus that the modules concerned are also touch-sensitive.
ESDs can be destroyed by voltages and power levels that are far below the level that can be per-
ceived by humans. Such voltages occur if a person touches a component or module without
earthing themselves. Components that are exposed to such overvoltages do not generally appear
to be defective immediately - incorrect behavior starts after the component or module has been in
operation for some time.
2.4.2 Important measures to protect against static charging
► Most plastics can easily become charged and must therefore be kept away from at-risk com-
ponents.
► Always ensure that people, the workplace and packaging are safely earthed when handling
electrostatic sensitive components.
2.4.3 Handling ESD modules
As a general rule: Only touch electronic modules if you must carry out work on the modules. In that
case, make sure that you do not touch the pins or printed conductors when you pick up flat mod-
ules.
Only touch components if you are earthed by one of the following measures:
●
You are wearing an ESD wristband.
●
You are wearing ESD shoes.
●
You are wearing ESD shoe earthing strips on an ESD floor.
Immediately before you touch an electronic module, discharge your own body by touching a con-
ductive and earthed object (such as unpainted parts of a switch cabinet, a water pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g.
plastic films, insulating table surfaces or items of clothing made from synthetic fibers.
Always place the modules on a conductive surface (table with an ESD coating, conductive ESD
foam, ESD bag or container).
Do not move the assemblies near to data view devices, monitors or television units. Keep a min-
imum distance of 10 cm to monitors.
2.4.4 Measurements and modifications to ESD modules
Only perform measurements on modules if one of the following conditions is fulfilled:
●
You are using an earthed measuring device (e.g. via PE conductors).
●
You are using a potential-free measuring device and discharge the measuring head before
the measurement (e.g.by touching an unpainted metal part of the controller casing).
► Always use an earthed soldering iron if you carry out any soldering work.
2.4.5 Dispatching ESD modules
► Always store modules and components in conductive packaging (e.g. metallized plastic bags
or metal sleeves) and dispatch them in conductive packaging
